Txhua hnub ceramics yog dav siv nyob rau hauv lub neej txhua hnub, xws li tableware, tshuaj yej teeb, kas fes sets, wine sets, thiab lwm yam. Lawv yog cov khoom ceramics uas tib neeg tuaj rau hauv kev sib cuag nrog cov neeg nyiam tshaj plaws. Txhawm rau txhim kho "zoo li tus nqi" ntawm cov khoom siv ceramic niaj hnub, cov khoom siv feem ntau yog dai kom zoo nkauj nrog paj paj ntawv thiab raug rho tawm ntawm qhov kub thiab txias. Nws tuaj yeem muab faib ua cov xim overglaze, xim underglaze, thiab underglaze xim khoom. Vim qhov tseeb tias feem ntau cov paj ntaub paj zoo nkauj muaj cov hlau hnyav, muaj kev pheej hmoo ntawm cov hlau hnyav hnyav thaum sib cuag nrog cov khoom noj.
Zoo thiab kev nyab xeeb txaus ntshai
▲Kev phom sij
Hauv cov txheej txheem tsim khoom ntawm ceramic tableware, cov hlau hnyav xws li txhuas thiab cadmium tuaj yeem muaj nyob hauv cov glaze thiab cov qauv zoo nkauj. Yog tias siv cov khoom noj, tshwj xeeb tshaj yog cov zaub mov acidic, nws tuaj yeem ua rau cov hlau lead thiab cadmium yaj rau hauv cov zaub mov thiab nkag mus rau tib neeg lub cev. Lead thiab cadmium yog cov hlau hnyav uas nkag mus rau hauv cov hlab ntsha yooj yim thiab tsis yooj yim tawm ntawm lub cev. Kev noj zaub mov ntev ntev uas muaj cov hmoov txhuas thiab cadmium tuaj yeem cuam tshuam rau tib neeg lub cev tiv thaiv kab mob, ua rau muaj ntau yam kab mob.
Cov tsos mob tseem ceeb ntawm cadmium lom yog arteriosclerosis, raum atrophy, nephritis, thiab lwm yam. Tsis tas li ntawd, cadmium tau pom tias muaj cov kab mob carcinogenic thiab teratogenic. Cadmium tuaj yeem ua rau kub siab thiab ua rau cov kab mob plawv thiab cerebrovascular; Kev puas tsuaj rau cov pob txha, daim siab thiab lub raum, thiab tuaj yeem ua rau lub raum tsis ua haujlwm.
Lead yog ib daim ntawv uas muaj kuab lom heev ntawm cov hlau hnyav, uas tuaj yeem ua rau muaj kev phom sij ntev tom qab raug nqus los ntawm tib neeg lub cev. Cov menyuam yaus uas raug coj mus rau lub sijhawm ntev yuav ua rau muaj kev cuam tshuam qeeb thiab tsis pom kev. Cov hmoov txhuas nkag mus rau tib neeg lub cev tuaj yeem ua rau lub hlwb ncaj qha, tshwj xeeb tshaj yog cov paj hlwb ntawm fetuses, uas tuaj yeem ua rau muaj kev tsis taus ntawm cov menyuam hauv plab. Tsis tas li ntawd, muaj kev pheej hmoo ntawm mob qog noj ntshav thiab hloov pauv.
▲Txuj cai
Kev txiav txim siab tias cov hlau hnyav hnyav tuaj yeem ua rau tib neeg lub cev raug mob, Suav cov qauv GB 4806.4-2016 "National Food Safety Standard Ceramic Products", FDA / ORACPG 7117.06 "Cadmium Pollution of Imported and Domestic Household Ceramics (Porcelain)", thiab FDA / ORACPG 7117.07 "Txoj Kev Ua Phem Txhaum Cai ntawm Cov Khoom Siv Hluav Taws Xob Hauv Tsev thiab Khoom Siv Hauv Tsev (Porcelain)" EU Cov Lus Qhia 84/500/EEC "Cuncil Directive on the Compliance and Performance Standards for Analysis Methods of Ceramic Products in Contact Food" thiab 2005/31 Council Directive 84/500/EEC hais txog kev hloov kho ntawm Kev Ua Raws Cai thiab Kev Ua Haujlwm Zoo rau Kev Ntsuam Xyuas Cov Txheej Txheem ntawm Cov Khoom Siv Ceramic hauv Kev Sib cuag nrog Cov Khoom Noj" qhia txog kev txwv kev sib cais rau cov hlau lead thiab cadmium. Txoj Cai California Prop.65-2002 California Drinking Water Safety and Toxic Substances Enforcement Act txuas ntxiv txwv kev tso tawm cov hmoov txhuas thiab cadmium, suav nrog cov kev cai tshwj xeeb rau sab hauv, qhov ncauj, thiab lub cev ntawm cov khoom; Lub German LFGB 30 & 31 "Food, Tobacco Products, Cosmetics, and Other Daily Necessities Management Law" tau ntxiv cov kev txwv ntawm cobalt dissolution nyob rau hauv lub hauv paus ntawm txhuas thiab cadmium dissolution.
Cov lus qhia rau kev yuav khoom thiab siv
(1) Ua tib zoo xyuas qhov zoo ntawm cov tais diav rau kev puas tsuaj, npuas, pob, thiab lwm yam. (2) Sim xaiv cov khoom uas tsis muaj xim kho kom zoo nkauj ntawm daim di ncauj sab hauv thiab sab nrauv, tshwj xeeb tshaj yog ceramic tableware nrog kho kom zoo nkauj sab hauv, uas ua rau muaj txiaj ntsig zoo thiab Kev pheej hmoo ntawm kev nyab xeeb Sim mus yuav cov khoom tsim nyog los ntawm cov khw muag khoom raug cai thiab zam kev yuav khoom nrog cov paj ntaub paj ntaub zoo nkauj rau ntawm e-commerce platforms. (4) Tsis txhob cia cov zaub mov acidic thiab cawv mus ntev siv cov tais diav ceramic nrog cov duab kos duab sab hauv. Lub sijhawm khaws cia ntev dua, qhov kub ntawm cov khoom noj ntau dua, thiab qhov yooj yim dua nws yog kom yaj cov hlau hnyav. Kev tshem tawm ntau dhau ntawm cov hlau lead thiab cadmium tuaj yeem ua rau muaj kev phiv tshuaj lom thiab ua rau kev noj qab haus huv.
